What is the difference between RPC and Web Service?

The creation of web services using the SOAP protocol requires one of two different methods to be executed. One can either heed the document SOAP protocol or the RPC SOAP messaging rules. RPC stands for the remote procedure call. In utilizing the use of RPC, there is the utilization of the client/server model.

The program that is calling for service to be completed is on the client-side, while the computer supporting the execution of a given application is said to be on the server end. The performance between RPC and web services is different, with a wide variation between web services and RPC being quite variable.

On the other hand, web service allows multiple deployments of service, with the only need to be met is that web service is used over an HTTP.
